内容摘要:
The celebrated Max-Cut problem asks for the largest bipartite subgraph of a graph. The extremal theory for Max-Cut is now quite well developed. For Max-Bisection, however, much less is known. A bisection of a graph is a bipartition of its vertex set in which the number of vertices in the two parts differ by at most 1. Bisection problems are more restricted than cut problems, and the available tools are consequently more limited. In this talk, motivated by several results and conjectures of Alon, Bollobás, Krivelevich and Sudakov, we study Max-Cut and Max-Bisection in H-free graphs and present some recent results in this area. This talk contains joint work with Jianfeng Hou and joint work with Jing Lin.
